STUNNING! Camila Giorgi, ranked 136th, pulled off a major upset at Arthur Ashe Stadium last night, eliminating sixth-seeded Caroline Wozniacki, a former world No. 1, to advance to the fourth round of the U.S. Open.Getty Images

Young, blond and talented. Maria Sharapova isn’t at the U.S. Open, but Flushing has found a suitable replacement.

Camila Giorgi, a dashing Italian with the game to back up her good looks, shocked sixth-seeded Caroline Wozniacki last night at Arthur Ashe Stadium, moving into the fourth round of a grand slam for just the second time in her young career.

Before one of her five match points, one fan yelled: “I love you, Camila.”

The diminutive 21-year-old Giorgi capped the upset, a 4-6, 6-4, 6-3 victory, with a whistling crosscourt forehand that was met with explosive cheers and whistles from the capacity pro-Giorgi crowd.

Ranked 136th in the world, the 5-foot-6 Giorgi reached the Round of 16 at Wimbledon last year and the third round a few months ago there. She had to advance through qualifying at the Open, before getting through the first two rounds without dropping a set.

Against the highly ranked Wozniacki, Giorgi was the aggressor. She went for the kill after dropping the first set, ripping home 46 winners, albeit with 45 unforced errors, and Giorgi also won 27 of 34 points at net.

“It’s amazing, this match, especially for the first time here in this court,” Giorgi, who now lives in Miami, said in her on-court interview. “The crowd was amazing, too.”

She will meet countrywoman Roberta Vinci, a quarterfinalist at the Open a year ago, in the fourth round.
